abstract = {Rechargeable high-performance batteries are essential for
portable electronic devices and gain increasing importance
in a transition scenario from fossil fuel based energy to
zero emission technology, including electric cars and energy
harvesting from volatile energy sources like solar and wind
power. Among the various possibilities envisaged,
solid-state batteries are currently seen as a highly
promising solution to overcome the current limitations of
conventional battery technologies such as the lack of
long-term stability, limited safety, and low storage
capacity. In solid-state batteries, the liquid electrolyte
is completely replaced by a ceramic ion conductor, so that
no highly flammable compound is present any more.This
publication gives an overview of the different classes of
solid lithium ion conductors, their properties, advantages
and disadvantages as electrolytes, and the challenges
associated with the processing of ceramic materials to full
battery cells and their proper operation: While appropriate
contact between electrodes and electrolyte can be easily
achieved in battery cells with liquid electrolytes, a
suitable contact with low charge transfer resistance in
general requires a thermally or electric field activated
deposition method for solids. Particularly, solid ion
conductors tend to react with air and moisture, and with
electrode materials during processing. Moreover – opposite
to earlier assumptions in literature – lithium metal
deposition inside of solid electrolytes may occur under
certain operating conditions, thus leading to short circuits
inside of the electrolyte. Sophisticated analysis methods
like Secondary Ion Mass Spectrometry (SIMS) and further
spectroscopic and diffraction techniques were introduced to
gain significant insight into these effects. Finally,
examples of fully functional solid-state batteries and their
electrochemical performance will be presented.},
